Sustainable design has long been a part of our practice at CBT. Since 1970, when our work met the standards set by the Vermont Act 250, the first sustainable legislation introduced in the United States, we have developed an approach to design that balances economic efficiency, environmental harmony and social benefit. Our most successful projects are full lifecycle models that integrate water, energy and materials to provide healthy, comfortable and productive environments. Our commitment to sustainability engages us with our clients in new ways as we introduce them to the financial and operational benefits of green buildings, lower energy, reduced waste and water use, lower environmental and emissions costs, improved operations and maintenance, and most importantly increased productivity from a healthier workspace. Currently we have over 47 LEED Accredited (Leadership in Environmental and Energy Design) professionals on staff and affiliations with the U.S. Green Building Council and the Massachusetts Green Roundtable.
